A uniform, vigorous series of double-flowered dahlias that brings a broad range of core single colors and exciting bicolors to the market. Venti is a series that fills the gallon and larger dahlia needs by putting on a large flower display, and it provides a more controlled habit than the competition. Sourced from a worldwide-proven dahlia cutting farm, Venti varieties have been trialed and grown throughout Europe and North America with excellent results.

Rooting Guidelines

PGR applications during rooting:
Sprays only. Cover the plants and avoid run-off as much as possible. For vigorous products, first application should be done about 7-10 days after sticking, second when needed. Please test before use.

Average Propagation Weeks:

4

Pinch in Propagation:

optional

Comments:

Begin feed regime as soon as roots are present to keep plant herbaceous. When propagating in short day season, give long days during liner growing.

Watering:
In general avoid drying out or overwatering the substrate as this will affect plant quality and finishing time. Root system will suffer when conditions change from one extreme to the other. “Growing on the dry side“ means letting the substrate become dry (substrate color turns light brown and substrate starts to separate from the pot edge) before watering.

“Keep constantly moist“ means watering the plants just before substrate becomes dry. Water management in rooting and finishing is half the success and the best way to prevent root-bound diseases, improve performance and control plant quality.

Finishing Guidelines

Temperature needs day/night:
During rooting keep soil temperature measured in the liner at 70°F/21°C until cuttings are well-rooted. After planting the liner, keep temperature up until roots have developed nicely. Afterward follow recommendations.

The use of “Cool Morning“ treatments will improve plant quality, flower and foliage color, and plant habit, and harden the plants. Lower the temperature by 8-12°F/4-6°C 2 hours before sunrise until 2-3 hours after sunrise. Start treatments after plants are rooted in, well-branched and cover the media (reach the pot edges). To avoid delayed flowering, keep the average day temperature under a close watch and if necessary, increase night temperatures. Finishing of the crop depends on the average day temperature, and positive or negative DIF methods as well as “Cool Morning” can be used to improve plant quality.
